I SPEOIFIGATION forming part of Letters Patent No. 662,4d1, datedNovember 27, 1900. Application filed January 2, 1900. Serial No. 52. N0model.)

Looms provided. with automatic iilling-sup-Yv ply mechanism have deviceswhich arejin tended to operate, when the filling is broken or exhausted,to provide the loom with a new supply of filling while the loom is inmotion. This has been accomplished by substituting for the shuttle intheloom anothershuttlecarrying a new supply of filling, or by providingthe shuttle in the loom with a new supply of filling, or, in otherwords, by changing the shuttle or by changing the bobbin in -theshuttle. These looms have a filling-supply detector on one side of thewarp which controls the actuating devices of the filling-supplymechanism. The absence of filling causes theldetector to set thefilling-supply mechanism in motion to renew the shuttle or the bobbin,as the case may be. Provisions are usually made toprevent the taking upof cloth when the filling is absent for apick or part of a pick and tostop the loom'when the filling-supply mechanism fails to providefilling. It sometimes happens that the filling will break at somedistance from the shuttle and that the trailing end will be interposed[objection in some forms of automatic fillings supply looms that it hasbeen doubted whether they accomplish a useful saving in the expense ofweaving. The thin stripe may also be caused by the clogging of thefilling-supply-detector fork.

The object oi my invention is to reorganize and improve the automaticfilling-supply loom to overcome the objectionable production of thinstripes in weaving,

To the above end the present invention consists, broadly, intheautomatic filling-supply loom having provisions for stopping the loomif for any reason the filling-supply detector fails to indicate theahsericeof filling.

My invention contemplates providing an automatic filling-supply loomwith a fillingsupply detector on one side of the warp adapted to controlthe filling-supply mechanism, and a illling-stop detector on the otherside of the warp to stop the loom in the absence of filling when thefilling-supply detector for any reason fails to operate. v

My invention contemplates providing an automatic filling-supply loomwith two fillingdetector mechanisms, one on each side of the warp, theone having provision to set the filling-supply mechanism in motion andiheother having provision to stop the loom, and connecting devicesbetween said detector -iuechanisins operating to prevent thestopdetector mechanism from stopping the'loom when the filling-supplydetector operates to set the filling-supply mechanism in motion.

My invention also contemplates certainother features and details ofconstruction hereinafter described, and pointed out in the claims.

It is to be understood that my invention is broad and generic incharacter and by no? looms above'referred totl1at is to say, it isadapted to those looms which operate by changing the shuttle as Wellsis-those Whichoperate by changing the bobbin in the shuttle.

The-specitlc form of loom which I have v illustrated in the accompanyingdrawings is, the well-known Northrop loom, in which the ion scription Ihave shown and described the -form of the invention which I prefer andnearer the warp when the shuttle is boxed at- "the opposite side oftheloom from, the fillingsupply mechanism, so therefore a trailingthread extending from theshuttle to the fillingsupplydetector willprevent the fillingsupply mechanism from .being set in motion.

OfQcourse if the trailing thread were long enough to extend into theshed it would be beaten up by the reed and weaving wou'lfl be resumed.If. the thread should break at the salvage, it .Will' be seen that'thenext time the shuttle was boxed at the opposite side'of the loom to. thefilling-supply mechanism'the- '25' trailingfithreadi'wouldextend upvto.,these1- vage,',afu "thju sbe' interposed between the the-lay, andprevent. the; detector fro|nset ting the filliug-supply mechanism{inmotion; 31f, on the other, hand, 'the thiead shouldbreak; not at thesalvage butb'etween' the and thus prevent the-making of thin-stripes."Now when the shuttle'is boxedat the filli ng-. supply side ofthe loomthe position of the thread-eyetherein causes the trailing threadfl .itolay alongside of the shuttle, andso the end ffilling-supplydGlZG'UlJOIfQHdf'lihefsllll tfl, Jthen io'f course thefilling-suppjl beset in operation"; 'butfi my invention to: cure the to'operate thefilling-asupply-detector,.fork,

In the accompanying drawings, illustrating the preferred form of myinvention, Figure 1' is a frontelevation of a portion of the Norcordancewith my invention. Fig. 2 is a side elevation of the loom looking fromthe fill- ,ing-supply mechanism side with parts of the connectionsbetween the stop-detector mechanism and the take-up mechanism.

shuttle enters the shuttle-box under the filling-eupply mechanism, noron the beat of the lay immediately after the filling-supply detector hasoperated to set the fillingeupply mechanism in motion, and so I employhere a detector operating to stop the loom on the second absence offilling, and l furthermore provide connections between this filling-stopdetector and the filling-supplydetector operating to render theslop-detectorinoperative when the filliug-supply detector operates toset. the filling'supply mechanism in motion. So in case of theoccurrence of a. trailing thread the stop-detector would operate to stopthe loom.

Having thus described the general features of my invention in itsbroader aspects, 1 now proceed to a description of the specific forrnshown in the accompanying drawings.

1 have shown in the drawings only so much and such parts of theWell-known Northrop loom-as is'necessary for a clear understanding ofthe cooperation therewith of my improvement.

The frame 1 supports the operative parts of the loom. The breast-beam 2has the pro jection 3, which altordsa guide for the shipper-lever e andit support for the knock-cit 16VQT'5. The filling-supply detector 6 isconstructed substantially as illustrated and described in patent toNorthrop, No. 529,9i3, and operates in the manner therein described toset the filling-supply mechanism in action and to stop the loom when thefilling-supply is exhausted. The filling-suppiymechnnisin 7 isconstructed substantially as shown in patent to Northrop, No. 568,4:55,the lever 8 corresponding to the lever show n separately in Figs. 5nndfiof said patent, the function -snpply dog to be raised by its springinto position to The detector shaft 9 is operated by the filling-supplydetector, as described in said Patent No. 568,455, through the lever 10,secured there- 'to. Upon one end of the detector-shaft 9 is secured thelever 11, which carries on its end the slotted linlt 12, which operatesin the usual manner to permit the ieverS to he moved by thefiiliugsupply dog. (See patout to Northrop, No. 568,455, wherein thelever dined slotted link oi'fcorrespond to the lever 11 and slotted link12 herein.) Upon the other end of thedetector-shatt E is mount ed theleqer' 13, which, by engagement with the projection 15 on thepawl-carrier ls lifts the pawl 16 out of engagement with the ratchet inthe manner described in patent to Northrop, No. 610,636. The take-upderic es 17 are 'Ljehstructed substantially as de scribed in hrd patent.The lay 18, the swords 19,,iih'e p itmen 20, the let-cit, the sheddingmechanism, and the Warp-stop de vices are otany usual or preferred form.

Upon the side of the warp adjacent to the fiiling'supply mechanism ismounted the iilliillin -stordetector slide is returned to its normalposition by a spring, :21, of which one end is attached to the slide andthe other to the slide-support. Loosely mounted on a suitable support,the detector-shaft f), is a lever 22, which has its upper end oppositethe pawl 3-5 of, the tillingstop detector. A spring 2i tends normally tohold the lever in the position shown in Fig. 2. A red 25 is secured tothe lower end of the lever 22 and it carries upon its rear end the wedge26, which when it is moved rearwardly is adapted to raise the stop-rod27 in'fron'i of the warp-feeler 28.- The stop-rod 27 is slid inglymounted in a-guide 29, secured in any suitable manner to the member 30of the frame of the loom. Thus when the lever 22 is oscillated by thefilling-stop detector it operates to lift the stop-rod 27, so thatthefeeler 28 will engage itand. the loom will be stopped tllereby in theusual manner. which illustrates the conneotionshetyreen the feeler 28and the knock-oft lever i of the Northrop loom and which issuhstantiuily the construction illustrated in the patent to Draper, No.618,378.) it is tohe understood that the filli-ng-stop detector may bearranged to connect with any convenient means of stopping the loom andthat the arrangement which I have shown and described is a convenientone and the one which I prefer;

The weft-hammer ill, its book 2, and the 02111133 operate in the samemanner as the Weft-hammer for the filling-supply detector, the cam 33 ofcourse being; mounted upon the cam-shaft 25% at one hundred and eightyde grees of angle to the position occupied by the cam which operates theWeft-hammer of the v fillingsupply detector.

From the side of the pawl 35 of the tillingstop detector there urojectsa pin 3b, which is adapted. to he eng .n by a Wire 37, pivotally mountedon the hr b" beam and having an end 38, projecting in front of the hook3905 the lever 8. This wire 3? is clearly shownin Figs. 1 and. 2.

' he operation of the filling-stop mechanism is as follows: Let it beassumed that the loom is running properly and weaving cloth and thatthereupon. the bob'oin of the shuttle hecorees exhausted or the fillingbreaks, and first let it be assumed that there is no trailing thread andthat the fillingbroke or necameexhnusted on the motion of the shuttlethrough (See Fig.6,

lOO

the shed away from the filling-supply mechanisni. lhe absence of Weftwill be indicated by the filling-supply detector, and its wefthnmtnerwill. move the slide -10 forwardly, s'o

that its end shall engage the lever 10, thereby oscillating the detectonshaft 9. This oscillation of the detector-shaft will set thefillinc-supply m rlmnism ii: f'l tion, because it will raise therear endof the' lever. 1-1 and raise the slotted link 12, and thereby permit thelever 8 to be moved by thespring on the dog of the filling-supplymechanism. The

l shuttlc will! now be thrown into the shuttlebox underthefilling-supply mechanism, and

on the next, beat of the lay the absence of. filling will be indicatedby the'filling stopdetector 21,:1.nd theweft-hainmerBl will push the 1filling-stopsliderearwardly and remove the wedge, 351 from under thepawl 35, thereby --per'mittingits operative'eiid to be dropped lowenoughtoengagethe lever 22.0n the next reciprocation of'the slide. Thefilling-supply mechanism would at this timepperate to pro- "vide' a" new"supply of fillingand sc on the next forward motion of the'weft-hammerthe weft-forkwouldfbe filted and its hook would fail to engage theweft-foltk, the slide would 2 stand still, and the hammer would pushthea wedge under the pawl 35 and restore it to its normal position. If,however, the filling had 1 "broken or become exhausted, as the; shuttlewasvpassing through the shed in the direcs3 5 tion to enter theshuttle-box under the fillingvsupply mechanism, such mechanism would notat this time operate to put a new bobbin inthe sh'uttle,'but the shuttlewould be thrown across to the oppositeside of the loom, and

then the filling-su'pply detector would operate to set thefilling-supplytmechanism in motion to insert anew bobbin the next't'imethe shuttle reached the box underthe filling-supply mechanism. So,therefore, in this case on the first 3 5 beat of the lay which wouldindicate an ab;

sence of weft opposite the filling-stop detector 21 the only operationwould be the dropping of'the pawl into operative position toen gage thelever 22. 'lhenjthe filling-supply '40 mechanism would be set in motionby the filling-supply detector and the oscillation'of the lever 8 wouldactuate the wire 37 to lift the pa 135, so that'on second absence ofweft op-.

- posits the filling-stop detector the pawl would be lifted by the wire,so that it should not engage the lever 22 on this reciprocation of theslide and the loom would not be stopped. The bent wire 37 constituteswhat may properly be called a stop-preventer, since itoper- 5o ates toprevent the stopping of the loom when the filling-supply mechanism hasbeen set in motion bythe filling-supply detector.,, On

v the occasion of a traili n g thread the fillingsup ply detector wouldfail to indicate the break in the filling, but the fillingstbpdete'ctorwould indicate it, and the first: reciprocation of thefilling-stop-detector slidewould operate to-drop the pawl 35 in positiontoen gage thelever 22, and the next successive reciprocation '60 of thefilling-stop-detector slide would cause the pawl to engage thelever 22and stop the loom, because the stop-preventer mechanism would beinoperative to lift the pawl 35 byreasdn of the'fact that thefilling-supply mecho5 anism had not been set in motionbyfthefilling-supply detector. I

The ordinary. Northrop loom is provi'ded I with a letting-back mechanismfor the take cut to Draper and Northrop, No. 678,838, which lets backthetake-up'to allow for the .absent weft-thread. This loom is alsoprodescribed, for lifting the pawl of the take-up ,mechanism, and Lhavefound it desirable in stopped by my filling-stop detector. To this end Ihave mounted in suitable bearings 41 on therear of the breast beam therock-shaft 42-, to which is secured at one end the lever 43, having thepin 44 at its end which is engaged by the dependent end of .the lever22, so that when the lever 22 is oscillated it will cause a From theother end of the rock-shaft .42 there projects the lever 45, which isadapted to engage the pinv 46, mounted in the side of the pawl-carrier14. Thus it will be seen that when the filling-stop detector operates tostop the loom the pawl-carrier 14 will be elevated so as .to disengagethe pawlflfi from the ratchet up will be stopped just before thestoppingof the loom, so that when the loom is started again the fellwill occupy its correct position to receive the filling. Having thusdescribed in its generic ,character and in thespecific form in which Ihave embodied it, I claim as new and desire to secure by Letters Patentof the United Statesv 1.
